RAIL-JOINT.

T 0 all whom it may concern:

Be it known that I, JOHN R. Cnossnn, a citizen of the United States of America, residing at Blythedale. in the county of Allegheny and State of Pennsylvania, have in vented certain new and useful improvements in Rail-Joints, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to rail joints, and the objects of my invention are to connect the confronting or abutting ends of rails in a manner that will provide practically a continuous tread for rolling stock, thereby eliminating the jarring and bumping experienced by rolling stock when passing over joints, and to provide simple and effective means for connecting the abutting or confronting ends of rails whereby one rail cannot become laterally or vertically displaced relatively to the other rail.

Further objects of my invention are to provide a rail joint that obviates the necessity of using splice bars, nuts and bolts for connecting the ends of rails, and to accom plish the above results by a mechanical construction that is durable, easy to install, and highly efficient for the purposes for which it is intended.

With the above and other objects in view the invention resides in a novel construction to be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure 1 is a side elevation of a rail oint in accordance with this invention. Fig. 2 is a cross sectional view of the same, and Figs. 3 and 4 are perspective views of the ends of separated rails.

A rail joint in accordance with this invention comprises rails that are generally designated A and B these rails having the webs 1 thereof provided with enlargements 2 and 3 at the ends thereof, said enlargements connecting the head 4 and the base flanges 5 of said rails. The enlargement 3 has a tapering dove-tailed tongue 6 that extends from the top of the head a to within proximity to the base flanges 5 of the rail A. The rail A has the base flanges 5 thereof cut away, as at 7 and 8, whereby the base flange 5 at one side of the rail will be removed from the enlargement 3 and the base flange at the opposite side of the rail protrudes beyond the enlargement 3 as at 9. This construction is best shown in Fig. 8 and reference will now be Specification of Letters Patent.

had to Fig. 4, showing the end of the rail B that is connected to the rail A. The enlargement 2 of the rail B has a tapering dove-tailed socket 10, said socket extending into the head 11 of said rail and the bottom of the socket terminating in proximity to the base flanges 12 of said rail. The base flanges 12 of the rail B are also cut away, as at 13 and at 14:, whereby the base flange 12 at one side of the rail will project or protrude beyond the enlargement 2 of the rail.

By cutting away the base flanges of the rails A and B, the ends of the rails can be easily fitted together, as shown in Fig. 1, with the tongue 6 seated in the socket 10 of the rail B.

After the rails A and B have been connected together, a rail chair is employed for further holding the rails in position. The rail chair comprises a plate 15 that has the longitudinal edges thereof provided with inwardly projecting overhanging flanges 16, said flanges extending over the base flanges 5 and 12 of the rails A and B respectively. The rail chair is placed in engagement with the base flanges of one of the rails, prior to connecting the ends of the rails together, and then it is shifted into the position shown in Fig. 1, whereby it will form a substantial base for the abutting ends of the rails. The rail chair can be located between two ties or supports, and in some instances the rail chair can be located upon a tie and spiked or otherwise secured thereto.

It is thought that the manner of assembling the rail joints will be apparent without further description, and I would have it understood that my invention is susceptible of such changes as fall within the scope of the appended claim.

What I claim is In a rail joint, the combination with rails having the ends of the webs thereof enlarged to the same thickness as the heads of the rails, each of said enlarged ends of said rails having the base flanges thereof extended at one side of the enlarged end, said extension being oppositely disposed, each of said enlarged ends further having the base flange thereof at one side cut away, one of said enlarged ends provided with a vertically disposed dove-tailed tapering socket extending from the base flange beyond the head of its respective rail, the other of said enlarged ends provided with a dove-tailed tapering tongue disposed centrally thereof and adapted to engage said tongue, the enthe combined length of the thickened por- 10 tion of the ends of the rails.

In testimony whereof I affix my signature in the presence of two Witnesses.
